Re: Casting a straight edge
Please do not introduce gravity as the cause, as that force is too weak. Interesting, but I never really gave it much thought! Crankshafts should always be stored in a vertical position. My understanding is that they can bow over time if in a horizontal position and not properly supported. No first...

Re: Casting a straight edge
Are you going to toss it out in the yard for a couple years to "season" it?
That seems to be a subject now open to considerable debate!

Re: Boring for Chuck Jaws?
When doing small diameter work, and I'm too lazy to install the 5C collet closer for one part, I use an ER16 chuck held in the lathe chuck.
It is much better way to hold small parts. Especially with a worn chuck.

Re: Vintage Steel Lapping Plate 12” x 18” x 4” Surface Plate Cast Iron Machinist Tool Maker Precision
My 12 x 18 blocks are the same configuration as below, so I used the same procedure lapping them together, for about half a day... Somehow I remember doing that, as they are a bit heavy to work with! Not claiming that this is the definitive proper way, just what I had a reference to after making the...

One of mine (12 x 18 plates) is double sided.
Two plates, three surfaces.
Actually, mine have three grooved surfaces and a non grooved flat surface.
